5.

the affairs of the Joint Venture will be governed by the direction and control of a management committee (the "Management Committee") to be composed of one representative and one alternate from each of the Participants, with decisions of the Management Committee to be determined by a majority of the percentage interests in the Licenses as voted by the representatives, except that if there is a deadlock, the deciding vote will be cast by the Operator;

If a Participant permits its interest to be reduced to 15% or less, then that Participant shall be deemed to have withdrawn from the Joint Venture and its interest will be converted to a 2% Net Smelter Returns Royalty;

(b)

If a Participant elects not to contribute its share of costs, or elects to contribute less than its agreed upon share of costs, and the other Participant is unwilling or unable to contribute to the shortfall which has been created thereby, that Participant may elect to continue with the programme based on its proportionate share of costs, and the interests of the Participants shall be adjusted so that each Participant holds an interest which is proportionate to its contribution to the total exploration costs.  If a Participant permits its interest to be reduced to 15% or less, then that Participant shall be deemed to have withdrawn from the Joint Venture and its interest will be converted to a 2% Net Smelter Returns Royalty;

10.

a Participant contributing its Proportionate Share of mine costs is entitled to receive, in kind, its proportionate share of any minerals produced from a mine on the property and to separately dispose of the same;

if a Participant defaults in paying its share of expenditures related to an Approved Programme and Budget in which it elected to participate, the non-defaulting Participant shall apprise the defaulting Participant of the default whereupon the defaulting Participant shall have 30 days to pay the moneys owed. If, after receiving the notice and opportunity to cure the default of the moneys remaining unpaid, the defaulting Participant's interest will be reduced according to the following formula:

Divide the sum of:

(i)

the agreed value of the Participant's Initial Contribution;

(ii)

the total of all of the Participant's Contribution under the Joint Venture; and

(iii)

the amount, if any, the Participant elects to contribute and does contribute (including such amount paid on account of default of another Participant) to the adopted Approved Programme and Budget;

by the sum of (i), (ii), and (iii) for all Participants; and Multiply the result by 100.
